Pain has long been a clinical, psychological, and social issue for human beings. Based on the progress of studies on pain mechanisms in neuroscience, more investigations are increasingly focusing on the pain-related psychological processes. Pain or nociception may have appeared pretty early in evolution, and may have long acquired its psychological and social attributes. From the innumerous amount of sensory inputs, our brain presents nociceptive information to our consciousness in the form of pain sensation. The extent of damage is reflected as pain affect. Similar protocols are also employed to reflect impacts in social relations. Different life experiences may thus generate great difference in pain cognition. Understanding pain from the view of both psychology and neuroscience may shed light on the depiction of pain per se.
